win10在同一個局域網中，前幾天正常使用，不記得修改了smbd的文件，但是突然無法訪問ubuntu共享的文件夾，win10檢查之后，報錯說可能遠程文件夾的smbd服務沒有啟動；我使用如下命令嘗試重新啟動smbd

sudo service smbd restart

輸出

Job for smbd.service failed because the control process exited with error code.
See "systemctl status smbd.service" and "journalctl -xe" for details.

推薦使用下面命令來進行具體排查

sudo smbd -iS
#或者
sudo smbd -FS

我的輸出報錯：

smbd version 4.7.6-Ubuntu started.
Copyright Andrew Tridgell and the Samba Team 1992-2017
invalid permissions on directory '/var/lib/samba/private/msg.sock': has 0755 should be 0700

說明不知道怎么回事，有個權限不對，按照輸出的指示做一下修改：

sudo chmod 0700 /var/lib/samba/private/msg.sock

再次重啟動smbd，但是錯誤依舊

sudo service smbd restart

再次使用sudo smbd -iS

嘗試刪除/var/lib/samba/registry.tdb

sudo rm /var/lib/samba/registry.tdb

最后再次啟動smbd成功！
